Subject: 	* ch-lang.c (chill_create_fundamental_type):  Track compiler
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b6236d6ec4f9d7f02e363da16f24c4f1e5a58fea;p=binutils-gdb.git

	* ch-lang.c (chill_create_fundamental_type):  Track compiler
	change that now emits debugging info with the type long for Chill
	longs.
	* dwarfread.c (read_tag_string_type):  Rewrite to allow forward
	references of TAG_string_type DIEs in user defined types.
